Spring 2016
The analysis of thousands of metabolites and lipids for discovery of metabolite biomarkers for disease monitoring and diagnosis requires the highest sensitivity and robust methods. Metabolomics is the study of metabolites found in the body, which can be used to discover biomarkers of disease or...

Development of Liquid Chromatography Mass Spectrometry Methods for the Identification and Quantification of Acylcarnitines in Biological Samples
DownloadFall 2012
The field of metabolomics follows the Greek premise where metabolic changes are believed to be indicative of disease. Acylcarnitines, for example, can be dysregulated in the presence of various diseases including genetic metabolic disorders and multiple sclerosis. Liquid chromatography mass...

Development of Mass Spectrometric Methods for Membrane Proteome Analysis and Protein Sequence Mapping
DownloadSpring 2014
This thesis work mainly focused on the development of mass spectrometric methods for membrane proteome analysis and protein sequence mapping. First, the comparison of the performance of RapiGest-, PPS- and SDS-based sample preparation methods for shotgun membrane proteome analysis was...

Differential 15N2-/14N2-isotope Dansylhydrazine Labeling and LC-MS for Quantification of the Human Carbonyl Metabolome
DownloadFall 2011
The objective of this work was the design and use of paired labeling reagents that are chemically identical but isotopically different to provide a simple and robust means of quantitative mass spectrometry (MS) based metabolome profiling. Herein is presented the differential 15N2-/14N2-isotope...

Evaluation of Derivatization Reaction Conditions for Metabolite Labelling Using Differential Isotopic Labelling for Biological Samples Analyzed by Liquid Chromatography Mass Spectrometry
DownloadFall 2013
The objective of this work was to assess the impact of reaction conditions for isotopic labeling of metabolites prior to analysis using liquid chromatography mass spectrometry (LC-MS). Differential isotope 12C/13C dansyl chloride was used to label metabolites containing either primary amines,...

Investigating Protein-Carbohydrate Interactions with Hydrogen/Deuterium Exchange Mass Spectrometry (HDX-MS)
DownloadFall 2014
The application of hydrogen/deuterium exchange mass spectrometry (HDX-MS) to investigating protein-carbohydrate interactions is described. Proteins from three bacterial toxins, the B subunit homopentamers of Cholera toxin (CTB5) and Shiga toxin type 1 (Stx1B5) and a fragment of Clostridium...

Isotope Labeling Liquid Chromatography Mass Spectrometry: Metabolite Identification and Human Salivary Metabolome Profiling
DownloadFall 2012
The objective of this work was to use paired labeling reagents that are chemically identical but isotopically different to provide a simple and robust way of mass spectrometry (MS)-based metabolome profiling. A differential 13C-/12C-isotope dansyl chloride (DnsCl) derivatization strategy has been...
